ANTI-AIRCRAFT BOMB on SHELL.

Specification of Letters Patent.

Patented May s, 1917.

Application led November 27, 1916. Serial No. 133,647.

Taall whom t may concern:

.Be it knownthat I, NrKoLAJ F. Ronz'ixnvrrcH, a subject of.the Czar of Russia, re-

siding at Farrell, in the county of Mercer and State of Pennsylvania, have invented certain new and useful Improvements in Anti-Aircraft Bombs or Shells, of which the following is a specification.

This invention relates to projectiles and has special reference to -an anti-aircraft i bomb or shell.

lOne important object of the invention is v to improve the general construction o f devices of this character.

A second important object of the invention is to provide a device of this character having an improved arrangement of tearing arms to rip the envelop or planesl of an' air craft.

is to'provide an improved device of the kind described wherein tearing arms are arranged to be held closed bythe cartridge case.

With the above and other objects in view, as will be hereinafter apparent the invention consists in general of certain novel details of construction and combinations of parts hereinafter fullyl described, illustrated ofthe forward .portion of the shell, the view being at right angles to Fig. 2.

Fig.v 4' .is a vertical section at right angles to Fig. 1. i

Fig. 5 is a transverse section through the body of the shell.

'In the embodiment of the invention here- -in illustrated- (there is provided a body 10 having a sha oint 11 at the front end or point of whic 1s a fuse typically indicated at 12, the'fuse being of any preferred kind such as a combined percussion and time fuse.

' Also located in this nose is a chamber filled with an-explosive 13, the chamber communieating by a passage `let, filled with slow A third important object of the invention positions in which they burning powder 15 with a casing 16 in a chamber 17 at the base of the shell or bomb.

The base of the shell is closed by a base plug 18 and around the casing 16 are packed shrapnel bullets 19, the casing itself being filled with an explosive 20.

Thus the shell or bomb has two explosive charges, the one in the` nose acting first andk blowing the nose to pieces while the one in the base acts afterward to blow the rear end of the shell or bomb to pieces and scatter the shrapnel.

Extending are broad channels 21 provided with rearward`extensions 22 offset to one side of the channels 21 and having oppositely disposed grooves 23 in their side walls. Extending part way across each of the channels 21 is a pin 24 whereon is pivoted the rear end of a respective tearing arm 25 provided at its free end with a claw 26. Pivotally connected to each of the arms 27 is one end of a respective brace 27, the remaining end of .each brace carrying a cross pin 28 slidable from the nose toward the base v in grooves 23. This end of the brace 27 enga ges the rear end of its channel 22 when the arms 25 are extended as in Fig. 1, the rear ends of said arms and braces being housed in the channels before firing.

In order to assist -in throwing the arms outward each arm has connected thereto one end of a tension spring 29, the remaining end of each spring being connected to the shell at 30.

At 31 is shown the cartridge case which partly envelops the shell and arms before liring, the mouth of' the case being crimped into the shell groove 32 and arm notches 33 when the parts are assembled as in Fig. 2.,

In operation, the cartridge is put into a proper gun in the form shown in Fig. 2 and fired. Upon leaving the gun the rotation given the projectile by the riliing will tend to throw the front ends of the arms outward by centrifugal action and this will be assisted by the springs, the two forces causing the arms to assume the position 4shown in Fig. 1. When in this position the rear ends of the braces will engage the rear ends of the channels and the arms will rest on the shoulders formed between the major and minor portions of said channels. When the fuse operates the front portion of the shell will first bel exploded and after a slight interval of time the rearl portion will explode. If the shell'hits anaircraft before exploding the arms will tear the planes or envelop to such extent as to Wreck the craft and in any case the explosion of the shell will produce great damage When occurring near an air craft.

There has -thus been provided a simple and efficient device of the kind described and for the purpose specified.

lt is obvious that many minor changes may be made in the form and construction of the invention Withoutdeparting from the material principles thereof. It is not therefore desired to confine the invention to the exact form herein shown and described but it is Wishedto include all such as properly come within the scope claimed.

Having thus described the invention, What is claimed as new, is

l. A bomb of the class described having longitudinal channels in itssides, tearing1 arms having their rear ends pivoted in the channels, braces having their front ends pivoted to the arms and their rear ends slidably mounted in the channels, and springs connecting the free portions of said arms and the body ofthe bomb adjacent the rea ends of the channels.

2. A bomb of the class described having longitudinal channels in its sides, tearing arms having their rear ends pivoted in the channels7 braces having their frot ends pivoted to the arms and their rear ends slidably mounted in the channels, springs connecting the free portions of said arms and the body of the bomb adjacent the rear ends of the channels, said arms and the body of the bomb being provided with grooves alining When the arms are folded, and a cartridge casing partly enveloping the bomb and arms and having its mouth crimped into said grooves.

in testlmony whereof l aliix my signature 1n the presence of tvvo Wltnesses.
